Understanding the Ecology of Polar Bear Populations in the Beaufort and Chukchi Seas to Support Management by the U.S. Fish and Wildlife Service

The USGS Alaska Science Center uses the latest technology in satellite radio-tracking to fill key information gaps on how polar bears use both the sea ice and land. Adult female polar bears are captured, fitted with satellite telemetry collars, and followed throughout their annual range. In collaboration with the U.S. Fish and Wildlife Service we are also experimenting with glue-on and ear tag satellite transmitters, which can be deployed on adult male bears and younger, still-growing bears. To estimate both the population size and vital rates of the population, we have used mark-recapture studies relying on physical capture of bears, primarily during the spring. We are currently moving towards using genetic identifications from tissues retrieved from remote biopsy darts and hair retrieved from barbed wire snares at bowhead whale carcasses. Results of past studies have also allowed us to delineate boundaries between populations and provide information needed to allocate harvests among stocks.
